I This inventionrelates'to'vulcanizers and more particularly an apparatus- 'ior"spot vulcanizing automobile tires, as shown in the accompanying drawings and described in the following specificationand claims.

Qtio'n is to-provide theusual steam-heated vulcaniz-er, comprlslnga steam chamber, an overhanging platen suspended from-a man- 1 frame. Theprimary object 'of the present invenactuated plunger bearing against a receiving I pad preferably mounted upon a wooden block secured to a ball and socket joint, supported at the end of a goose-neck member of the Figure 2 is a similar side elevation with parts broken away showing the plunger drawn from contact with the receiving pad ually adjustable screw/shaft supported at the end of a swinging 1a'rm,1in turn mounted upon a post rising above the steam chamber,

i with :a plunger heatedby the steam in the I a chamber and slidable in a cylinder extending through and' integral" with the 'wallpf by a spring whichforc'es'it' laterally against a receiving pad supported at the end of a goose-neck arm attached to the frame ofth e' "device;a foot lever ,s'erving 'to withdraw *the plunger fr'omcontact with the receiving pad as required to admit the "parts tobe vulcanized. t
